Abstract
A reproduction apparatus and method provides first and second toner image bearing members (TIBMs). Each of the TIBMs has a respective toner image that is moved through a respective transfer nip with a web that has or supports a toner image receiving surface. Each TIBM in each nip has a predetermined amount of pre-nip wrap by the web and a predetermined amount of post-nip wrap by the web. Electrostatic transfer, preferably in a constant current transfer mode, of a toner image at each transfer nip is made to the receiving surface so that a toner image transferred by the second TIBM is deposited on the receiving surface so as to form a composite image with the toner image transferred to the receiving surface by the first TIBM. Between the nip with the first TIBM and the nip with the second TIBM, a second surface of the web opposite the first surface is subjected to a discharge member at a fixed predetermined potential preferably ground to reduce charge on the web to condition the web for receipt by the receiving surface of a second toner image from the second TIBM.
